turned into a full manga!! it was suspicious at first but it ends up being just cute. she's the urban legend of the woman in japan who goes up to you and asks you if you find her beautiful, and then takes off her mask to show you her slit mouth.
dont care about the tags, she never dies as long as people remember her, so she gets into a relationship with the ml when he's an adult (she's only seen him once when he was a child).
